| Summary: | Samples for sinking mass flux of size-fractionated (>0.7µm and >10µm) Chlorophyll-a and Phaeopigments were collected with short-term drifting sediment traps between 75° and 85°N in the northern Barents Sea with R/V Kronprins Haakon in March 2021 as part of the Nansen Legacy project (cruise 2021703, Q1). High-density bottom water was collected at the station and filtered (Whatman GF/F 0.7µm), and then filled into the trap cylinders (KC Denmark, aspect ratio >6) prior to their deployment. Afterwards, the sediment traps were deployed with 2 cylinders at each depth (30m and 120 or 200m) for a duration between 12 to 39 hours. Depending on the sea ice conditions, the sediment traps were deployed in open water, anchored to a sea ice floe or within an ice lead. Upon retrieval, the content of the cylinders from each depth was pooled and stored at 4°C in dark until further analyses. Between 100-300ml were filtered onto 0.7µm GF/F filters (Whatman) for the analysis of Chla and Phaeopigments, depending on the ... : 4 NetCDF Data Format data, totaling ...... 27.32 KB 4 ASCII text, with no line terminators, totaling ...... 128 B ... |
